Tools for manual annotation

A set of tools for QC and manual annotation

All manual edits can be used for active training of AI models. In other words, every manual correction that you do on the point cloud can be applied to future projects.

Point cloud annotation can be done easily with the use of intuitive tools. From each selection, a cross-section view can be generated for easier final selection.

Annotations can be done in a perspective or orthographic 3D view.

You can either annotate and assign points to classes from scratch or annotate point clouds that were automatically classified using an AI model.

A variety of tools are available:

Rectangle selection
Strip selection
Polygon selection
Clipping

Each action can be triggered using keyboard shortcuts to further reduce the time needed for annotations.
